On 4m and 6m the HDMI cable radiates noise that is picked up by the antenna on the tower.

But on 4m I still have some birdies from it.David Anderson GM4JJJhttps://www.blogger.com/profile/01308957902320184832noreply@blogger.comtag:blogger.com,1999:blog-3322535002789091724.post-67380880661425668212017-07-02T20:22:40.877+01:002017-07-02T20:22:40.877+01:00Agreed; my large ferrites are fairRite type 31, bu...Agreed; my large ferrites are fairRite type 31, but the smaller cheep rally sourced ones are completely unknown.g0mgxhttps://www.blogger.com/profile/02099618962895092351noreply@blogger.comtag:blogger.com,1999:blog-3322535002789091724.post-5471060716058035472017-07-02T19:03:07.080+01:002017-07-02T19:03:07.080+01:00I wonder if these bargain unmarked ferrites found ...I wonder if these bargain unmarked ferrites found at rally&#39;s and on eBay are using genuine type type 31 material? It would be useful to compare them against the real things from for example FairRite Grade 31 which are considerable more expensive.David Anderson GM4JJJhttps://www.blogger.com/profile/01308957902320184832noreply@blogger.com
